I didnt even know you got your car back from the dealer after seeing your post help needed asap,how much coolant did you loose roughly(couple of quarts)if so while the car is COLD fill up the coolant reservoir to the top,then start up the car and let it warm up for ten min while your sitting and observing the gauge with the HEATER on full blast making sure the gauge does not exceed the half way mark,if so SHUT HER OFF and wait 15 min and with CAUTION gently turn the reservoir cap until you hear air being released and close it again,now drive the car for 5-10 min close to HOME while monitoring the gauge carefully,now upon returning home let her COOL of again for 15 min and gently open the reservoir cap to let some air out and close again,if the gauge did NOT EXCEED past the middle follow the steps above a couple more times later in the day,important to note is the next morning,DO NOT start the car,check the COOLANT LEVEL while the car is COLD,top off if necessary,follow the steps above the next day again,CLOSELY MONITORING the coolant level and gauge,you will find out PATIENCE IS THE KEY in this procedure,now need to get me a nice cup of JOE to wake up.lol Z
